Iowa ApplicationApr-ill, 1941,8erialNo.387,536 I I 2.0mm- (01.15'1-6) i My inventionrelates to improvementsin tire removing tools, the principal object inview being to provide a lightweight, strong tool for strad-' dling apneumatic tire and which is easily operative into locked position tocompress the beads of the tire together so that said beads may enter thelow part of a drop center rim at one side thereof and the tire may bepried oi! the rim at the other side, as for instance, with the usualtire iron. I

To the accomplishment of the above, and suh-' ordinate objects presentlyappearing, a preferred embodiment of my invention has been illustratedin the accompanying drawing, set forth in detail in-the succeedingdescription, and the claims appended hereto.

In said drawing: 4Fi8ure1isavlewinside v the preferred embodiment of myimproved tire removing tool and the use thereof,

Figure 2 is a view in edge elevation,

Figure 3 isaview in transverse section taken on the line 3-3 ofFigure 1. j

elevation illustrating I center position relative to the pivots I and I2to thereby form an overthrow dead center lock when the free ends of thehooks 3 and 5 are close together.

The hooks l, 5, with elongated, transversely extendin rounded tips IIwhich may be easily wedged in between a tire I and the sides of a dropcenter rim it without damaging the tire.

The use and operation of my improved tool will be readily understood.The levers I, 2:, are

separated on the pivots 8, ill,- l2, to swing the hooks I, 5, away fromeach other on the pivot i so as to place the latter upon opposite sidesof the tire I. The longer lever I is held stationary and the shorter one2 moved toward the long one to cause the hooks 3, i, to approach eachother in a manner which will be clear and squeeze the sides of the tirel4 therebetween. At the same time, the tips ll of the hooks i, areforced in between the beads of the tire I4 and the sides I of the-rim l5asshown in Figure 1. When the levers l, 2, have .been swung toward eachother in degree suilicient for the links to form the overthrow deadcenter lockdescribed, the tool is locked in clamping relation to thetire H, as

will be clear, against opening, the tips l3 holding Referring thedrawing by numerals, the illustrated embodimentof my improved toolcomprises a pair of. relatively long and short, ilat levers I, 2, ofchanneled form opposed. edgewlse in acommon plane, channels facing, thelong lever terminating in a front end grappling hook 3 and beingprovided with a pair of opposed earlike extensions 4 on its inner edgespaced inwardly from the hook I. A flat, metal grappling hook 5 ispivoted at one end, as at 6, to the ears 4 to swing therebetween in theplane of the levers I, 2, toward and from the book. The short leverl hasa divided front end straddling the grappling hook 5 and pivoted, as at8, to the same intermediate the endsthereof. A flat, straight link. hasone end pivoted, as at III, to a pair of edge ears H on the short lever2 spaced inwardly from the pivot 8, and its other end similarly pivoted,as at l2, between the sides of the long lever I inwardly of the pivot8.' The pivots], ll,

.are closer together than the pivots 0,, so that the levers l and 2 maybe moved apart to 'swing the hook! away from the hook j, and wherebysaid levers may be moved toward each other to similarly operate saidhooks}, s, and to swing the links 8 on the pivots II, II, until thepivot II is swung inwardly and forwardly past a dead 'the'beads of thetire ll close together, as shown in Figure 1, so that the portion of thetire clamped by the tool may enter the drop center 11 of the-rim II andpermitthe opposite side of the tire to be easily pried oil of the rim. vi

The foregoing will, it is believed; suflice to im- 7 part aclearunderstanding of my invention without-further explanation.

Manifestly the invention, as described. is susceptible of modificationand if no departure is made-from the scope of the claims.

What I claim is:

I. A tool of the classdescribed comprising a pair of relatively long andshort flat levers opposed in edge to edge relation, the longer leverterminating in a grapping hook end, a second grappling hookpivoted, atone end to the longer lever in the rearof the terminal hook thereof,

the shorter lever being pivoted, at one end to the second grappling hookintermediate'the ends of the latter, and-a link having its endspivotally connected to thelong and short levers, respectively, in therear of. the pivotal connections of the second grappling hook and saidshort lever, said pivotal-connections of said link to said levers beingspaced diflerent distances from the, pivotal connections of said secondgrappling lever and that of the short lever.

are provided on their free ends I posed in edge to edge relation, thelonger lever g terminating in a grappling hook end,-a second grapplinghook pivoted at one end to the longer lever in the rear of the terminalhook thereof, the shorter lever being pivoted at one end to the secondgrappling hook intermediate the ends of the latter, and a link havingits ends pivotallyconnected to the long and short levers, respec- 10 ma-sac tively, in the rear of the pivotal connections of the secondgrappling hook and said short lever, said pivotal connections of saidlink to said levers being spaced diilerent distances from the pivotalconnections of said second grappling lever and that of the short lever,said hook members being provided with elongated rounded tips extendinglengthwise transversely thereof.
